 desc = "The remote host is missing an update to the system
as announced in the referenced advisory FreeBSD-SA-06:18.ppp.asc

The ppp(4) driver implements the Point-to-Point Protocol for using serial
lines (e.g., modems) as network interfaces.

While processing Link Control Protocol (LCP) configuration options received
from the remote host, ppp(4) fails to correctly validate option lengths.
This may result in data being read or written beyond the allocated kernel
memory buffer.

Solution:
Upgrade your system to the appropriate stable release
or security branch dated after the correction date
